KEEP ELECTRICAL SYSTEMS PRESSURIZED AND ENERGIZED DURING REPAIRS

Reliable electrical systems are essential in providing critical power supply to public consumers as well as to large industrial production facilities. Colt’s on-line leak repair of electrical equipment involves the process of identifying and addressing leaks in electrical systems, such as transformers, switchgear, or cables, while the equipment remains energized and in operation, minimizing downtime and maintaining the continuity of electrical supply.

Conventional electrical equipment leak-sealing repairs require equipment to be drained of oil and taken off-line. Colt specializes in providing safe and innovative approaches to on-line leak sealing and repair while keeping systems pressurized and energized – when safe distances are maintained. Our goal is to eliminate any downtime and to keep critical electric equipment running.

DRILL AND TAP REPAIRS

Over time, flapper valves and flanges can deteriorate and cause a leak. We utilize a drill and tap procedure to effectively seal leaks on pressurized equipment. Colt technicians utilize a special dielectric, Dissolved Gas in Oil (DGA) Sealant that is nonconductive. Both uncured and cured it creates no noticeable change in condition of the transformer insulating oil. Because it is not a silicone it will not foam, but it is pliable and expands while curing.

CLAMPS AND ENCLOSURES

Clamps can be designed for various purposes and can be custom fabricated to meet your needs: 

• Threaded joints 
• Pipe fittings 
• Flanges 
• Welds 
• Bushings 
• Radiator Fins

WEIR REPAIRS

Over time, flapper valves and flanges can deteriorate and cause a leak. We utilize a drill and tap Weir repairs offer a solution for extending the life of corroded or weakened fins and associated structures. Colt designs, fabricates, and installs Weirs, utilizing urethane and other sealants to facilitate the repair.

SF6 GAS MITIGATION

Leaking SF6 assets present challenges to carbon neutrality. Colt helps seal these leaks on-line utilizing wire wraps, drill and tap or clamps depending upon the best method to repair the specific leaking asset. On breakers, we typically utilize a clamp. Our team is here to help mitigate SF6 leaks quickly to minimize environmental impact and keep key power systems operational. Colt’s electrical equipment repairs can be done on SF6 gas, transformer oil, and nitrogen.

INVESTING IN INNOVATION

Just as we invest in training and growing our knowledge base, we also strategically invest in the utilization of new and innovative technologies. This investment in emerging technologies drives operational excellence by enhancing operational efficiency, productivity, and effectiveness. Adopting and integrating emerging technologies:
